Accurate estimation of cratering asymmetry on the Moon is crucial for understanding Moon evolution history.Early studies of cratering asymmetry have omitted the contributions of high lunar obliquity and inclination.He...

At 12:07 UT(8:07 pm China Standard Time)on 2017 Oct 4,a bright bolide was widely observed in the Shangri-La region of the Province of Yunnan,China(Figure 1).The event was well observed by the general public as it took...
The surface of the Moon is highly cratered due to impacts of meteorites, asteroids, comets and other celestial objects. The origin, size, structure, age and composition vary among craters. We study a total of 339 crat...
We present simulation results on evolution development of orbital motion of short-period comets with the revolution period not exceeding 6-7 years, namely comets 21P/Giacobini-Zinner, 26P/Grigg- Skjellerup and 7P/Pons...
In the present age,the potential threat to space projects coming from some intense meteor storms has been noticed.Especially,the increasing activities of mankind in space for scientific,commercial and military purpose...
Two-station observation of meteors, especially a meteor trains, provides an effective approach to the measurement of the physical parameters. We have collected four special groups of photographs of meteoric trains tak...
The Leonid meteor shower in November 1998 was observed widely by astronomers. The first peak, rich in bright meteors, appeared about 16 hours before the predicted maximum of the main shower. The main shower was also o...
On March 8th, 1976, a shower of meteors fell into the atmosphere of the earth with a velocity of 10 km/sec. The shock wave induced by the friction between the meteorites and the dense air was so intense that the tempe...
